KATDRILLS Pilot adapter tools
Reaming drilling tools are deployed to enlarge the borehole diameter to the required size, following the completion of a pilot hole drilled to the target depth. Our product portfolio includes foru rock reaming tool variants: pilot reaming drilling tools, dome reaming button bits, adapter reaming button bits, and Conical Reamer Drill Bit.
Pilot reaming drilling tools adopt a split structure, integrating pilot adapters and reaming button bits as two separate components. By contrast, both dome reaming button bits and adapter reaming button bits(hole open bit) feature a one-piece design for enhanced structural stability.
Parameters
Tapered: 6° taper angle reaming button bit for R25, R32, SR32 pilot adapters
12° taper angle reaming button bit for R28, R32/SR32, SR35, SR38 and TC42 pilot adapters.
Pilot adapter are specialized drilling tools designed for post-pilot-hole operations, serving the following core purposes in various drilling scenarios:
- Borehole diameter expansion
- Borehole wall finishing
- Adaptive drilling for complex formations
- Synergistic operation with pilot drilling tools
Features
Precise Hole Deviation Control
Rigid concentric guiding structure ensures coaxial alignment of pilot bit and reaming bit, limiting hole deviation to ≤0.3°/m in rock formations.
High Torque & Shock Load Bearing
Reinforced threaded/tapered connection withstands peak torque in rock drilling, preventing adapter fracture or disconnection.
Quick Tool Change for Rock Drilling
Tool-free assembly/disassembly design cuts bit replacement time by 30%, improving rock drilling operational efficiency.
Customizable for Complex Rock Conditions
Tailored length and interface specifications for different rock types (soft/hard/mixed strata) and drilling depth requirements.
